In the Open Road Films feature, written by Scott Z. Burns and Soderbergh, Mara plays a woman who seeks help from a psychiatrist (Jude Law) in order to cope with her husband’s imminent release from prison (Channing Tatum). She takes prescription pills to ward off anxiety, but begins to experience bizarre side effects and wakes up one morning to find evidence of an apparent murder. What exactly happened, by whom, is a mystery.

The film, which will be released in February 2013, reunites Soderbergh and Burns — they worked together on “Contagion” and “The Informant!”
